[Application Note] Pre-treatment for Tobacco-Specific Nitrosamines in Urine

Pre-treatment for the analysis of tobacco-specific nitrosamines in urine using UPLC/MS/MS with ISOLUTE SLE+.

TSNA, or tobacco-specific nitrosamines, are carcinogenic substances found in tobacco products, including electronic cigarettes and smokeless tobacco. TSNA may show false positives due to secondary and tertiary contamination, similar to nicotine. In methods with sufficiently high detection sensitivity, secondary contamination or passive smoking can cause non-smokers to test positive for TSNA. Tertiary contamination arises from various instruments used throughout the sample pretreatment and analysis process, such as test tubes, solid-phase extraction, pipette tips, and more. ISOLUTE SLE+ retention liquid extraction plates and columns provide an efficient alternative for bioanalytical sample pretreatment, replacing traditional liquid-liquid extraction (LLE). High recovery rates can be achieved without the formation of emulsions, significantly reducing the effort required for sample pretreatment. *You can download the English version of the catalog. *For more details, please refer to the PDF materials or feel free to contact us.

The SUS coating was hindered by the "passivation film" from adhering properly.

Explanation of measures against poor adhesion and peeling due to the unique passive film of stainless steel.

Stainless steel has high corrosion resistance, but it is a material that is difficult for paint to adhere to. There are cases where the passive film on the surface repels the coating. Sandblasting or a special primer may be required. Pre-treatment specifically for stainless steel is important. We also provide detailed examples of improvements in publicly available materials.

Insufficient degreasing is the root cause of all painting defects and reduced adhesion.

The reason for the persistent paint peeling and pinholes may be the invisible residue of oil.

Degreasing is an important process in the pre-painting stage that greatly affects the adhesion of the paint film. If the removal of oil, dust, and oxide films is insufficient, the adhesion of the paint film will decrease, leading to many defects such as paint peeling, pinholes, and variations in film thickness.

Insufficient cleaning is the cause of all painting defects and the truth behind recontamination.

The peeling paint and pinholes are not decreasing. The cause may not be due to degreasing, but rather residual chemicals from insufficient cleaning or recontamination.

The cleaning process is a crucial step that removes residual chemicals and fine dirt left after degreasing. However, in practice, there are many cases where it is judged that "there is no problem because we are rinsing with water." In reality, insufficient cleaning can lead to the residual chemical components remaining on the material's surface, which can vaporize during curing, resulting in pinholes or paint film lifting. This is particularly likely to occur with complex-shaped parts, where defects due to liquid pooling can easily arise. This is actually a point that is often overlooked. There are cases where the cleaning water itself is contaminated. Furthermore, in some cases, the final rinse water is managed based on a conductivity standard of 50 microsiemens per centimeter or less. Deterioration of water quality can lead to adhesion failures or whitening phenomena. A common misunderstanding in the field is the belief that "as long as degreasing is done, there is no problem." By reviewing the cleaning conditions, there are many cases where the defect rate can be improved. Actual improvement cases are also detailed in publicly available materials.

Insufficient drying was the culprit behind the pinholes, the essence of the cleaning process.

Are you overlooking the drying process after cleaning? In fact, residual moisture may be causing pinholes and blisters.

The drying process after cleaning is an important management item that affects painting quality. However, on-site, there are often cases where it is judged that "there is no problem because it looks dry." In reality, there may be fine moisture remaining on the surface of the material or inside gaps. If painting is done in this state, moisture can evaporate during curing, leading to pinholes, blisters, or delamination of the paint film. This is actually a point that is often overlooked. Complex-shaped parts tend to retain moisture inside. Furthermore, in drying ovens, temperatures are often managed at around 80 to 120 degrees, but there may be cases where the oven temperature does not match the product temperature. A common misconception on-site is the belief that "it's safe because it has passed through the drying oven." By reviewing the drying conditions, there are many cases where quality can be stabilized. Actual improvement cases are also detailed in publicly available materials.

Insufficient rust prevention is the cause of all rust reoccurrence: the truth within the coating.

Has rust reappeared after a while since painting? The cause may not be the paint film, but rather corrosion of the substrate due to insufficient rust prevention treatment.

Rust that reappears after painting may not be due to the paint film itself, but rather insufficient anti-corrosion treatment. However, on-site, it is often mistakenly judged that "since it has been painted, it won't rust." In reality, if fine red rust or corrosion components remain on the surface of the material, corrosion can progress inside the paint film and manifest as reappearing rust months later. This is especially significant at welded joints and cut surfaces, where the effects of insufficient anti-corrosion treatment are more pronounced. This is actually a point that is often overlooked. Even if it looks clean on the outside, corrosion reactions are progressing inside the paint film. Furthermore, if anti-corrosion primer is not applied after blast treatment and left unattended, reappearing rust can rapidly progress in conditions of over 60 percent humidity. A common misconception on-site is the belief that "if the topcoat is thick enough, there will be no problem." By reviewing the anti-corrosion process, there are cases where reappearing rust can be significantly improved. Actual improvement cases are also detailed in publicly available materials.

Aluminum die casting coating's pre-treatment was everything for quality.

The quality of the pre-treatment greatly affects adhesion. What processes should be checked before the paint and equipment?

In aluminum die casting painting, it is not an exaggeration to say that the pre-treatment determines the quality. No matter how high-performance the paint used is, if the pre-treatment is insufficient, it can lead to poor adhesion and paint film peeling. One often overlooked factor is the specific contaminants of the material. Aluminum die casting tends to retain release agents and processing oils, and if painting is done without adequate degreasing, the paint film will not adhere properly. Additionally, the oxide film can also cause a decrease in adhesion. Furthermore, in baked coatings, heating to around 180°C can cause internal gases to expand, potentially leading to blisters and pinholes. Therefore, gas countermeasures during the pre-treatment stage are also important. On-site, there is often a tendency to focus solely on the painting process, but many issues arise before painting. By properly performing degreasing, surface adjustment, and chemical treatment, adhesion and durability can be improved. To stabilize quality, it is necessary to manage not only the painting conditions but the entire pre-treatment process. We have published materials summarizing cases where improvements were made by reviewing the pre-treatment process. If you have similar challenges, please refer to them.

Is the paint peeling due to insufficient pre-treatment?

Most paint peeling is caused not by the paint itself but by inadequate pre-treatment. This explains the poor adhesion due to insufficient degreasing and chemical treatment.

Paint peeling is a typical defect caused by issues in the pre-painting process, such as insufficient degreasing or inadequate chemical treatment. If press oil or cutting oil remains during curing, the oil will volatilize at around 180 degrees, creating tiny spaces between the paint film and the substrate. As a result, peeling occurs due to vibrations or impacts. Even if the surface looks clean, there may still be residual oil or oxidation films, making it important to manage the numerical values of pre-treatment conditions.

Reoccurrence of paint peeling and abnormalities in the previous process.

The paint peeling that does not improve even after reviewing the baking temperature. I will explain the relationship with the often-overlooked previous processes.

If paint peeling recurs, simply reviewing the baking temperature may not lead to improvement. Even if conditions such as 180 degrees for 20 minutes are followed, insufficient degreasing or poor chemical treatment can reduce adhesion. Abnormalities in previous processes may surface months later as peeling, blistering, or rust reoccurrence. It is necessary to confirm the entire process, including degreasing, drying, and chemical treatment, rather than just raising the temperature as a countermeasure.

The relationship between pinholes and internal gas.

Pinhole defects that are likely to occur in die casting and casting. This explains the relationship between internal gas and pre-treatment.

A pinhole is a defect that occurs when small holes appear on the surface of a coating. In die casting and casting, it occurs when gas trapped inside the material expands during baking and breaks through the coating. When residual gas loses its escape route at around 180 degrees Celsius, it can lead not only to appearance defects but also to a decrease in rust prevention performance. The presence of oil and moisture can also cause similar issues, so reviewing preheating and drying conditions is effective.

The blind spot of pinholes and insufficient drying.

Insufficient drying after cleaning may be the cause of pinholes. I will explain the defects caused by residual moisture.

Insufficient drying after cleaning is a commonly overlooked cause of pinhole defects. In parts with complex shapes or bag holes, moisture tends to remain, and at baking temperatures around 180 degrees, it can rapidly evaporate and break through the coating. Residual moisture can lead not only to pinholes but also to blisters, adhesion failures, and the recurrence of rust. In environments where humidity exceeds 70 percent, managing drying time and air blow conditions is crucial.

The cause of the blister that will appear in a few months.

Blisters that occur months later, even if there are no issues at the time of delivery. This explains the relationship between internal corrosion and pre-treatment.

Blisters may not appear immediately after painting, but can occur months later. If there is slight moisture or foreign matter left inside the paint film, and if there is insufficient chemical treatment or degreasing, adhesion can decrease, allowing moisture and oxygen to penetrate and cause corrosion. As a result, this manifests over time as blisters on the surface. This is not a sudden defect, but rather a manifestation of issues that began before painting, indicating that a review of the entire pretreatment process is necessary.

The real reason why pinholes don't decrease! Insufficient degreasing leads to defects.

Countless small holes appearing on the painted surface. We will address the fundamental causes that cannot be solved by merely adjusting the viscosity of the paint.

[Cause of Occurrence] Pinholes (bubbles) that occur on the painted surfaces of automotive parts are defects that significantly impair appearance quality. On-site, the mixing ratio of thinner and the viscosity of the paint are often suspected, leading to repeated adjustments in the formulation. [Truth] In reality, many pinholes are caused by air trapped in oil or moisture that remains in the gaps of the material, or by air trapped in the "voids" characteristic of aluminum die casting, which expands during curing and breaks through the paint film. This phenomenon is often mistakenly identified as foreign matter contamination. [Improvement Measures] To prevent this, it is essential to extend the setting time by 3 to 5 minutes longer than usual to allow volatile gases to escape slowly, and complete drying during pretreatment is crucial. For temperature management guidelines aimed at fundamentally eliminating pinholes, please download our free materials for more information. [Summary] Addressing pinholes is not only about adjusting the paint but also about controlling the discharge of air and moisture trapped in the material. Eiwa Kogei Co., Ltd. will solve all your concerns related to metal painting, including poor adhesion of zinc die casting and aluminum die casting.

Three points for pre-treatment to prevent poor adhesion of aluminum die-cast coating.

Peeling of aluminum die-cast paint occurs due to insufficient management of oil content, voids, and surface conditions.

■Cause of Occurrence: Poor adhesion of aluminum die casting is judged to be weak and easily peeling paint. The causes are not only the paint itself but also the residual oil from casting and processing, the presence of pores and gas escape on the material surface, and the surface condition after pretreatment. It is a material that tends to retain dirt and moisture in complex shapes, particularly around holes, corners, and ribs. ■Truth: It is difficult to detect at the time of shipment, and if oil or moisture remains under the paint film, it will peel off due to assembly or transport vibrations. In areas with pores, it can develop into pinholes or blisters. The quality of the paint is almost determined by the management before application. ■Improvement Measures: By confirming the three points of degreasing to remove oil, ensuring no moisture remains after cleaning, and checking for pores and roughness at each process, it can be recorded in the lot records to prevent recurrence. Please utilize materials that can confirm pretreatment, material condition, and film thickness conditions.

In an era where the adoption of aluminum parts is advancing, the concept of substrate management to prevent paint peeling.

In the lightweight automotive parts, the adhesion of aluminum coatings and the management of pre-treatment become important.

■Cause of Occurrence: The importance of aluminum parts is increasing due to trends in weight reduction and cost management. Aluminum is lightweight and has excellent workability, but if painted with the same approach as iron, issues such as poor adhesion, paint peeling, pinholes, and blisters can occur. The three points to check are the residue of processing oil, the condition of the oxide film, and the drying after pretreatment. ■Truth: Peeling is not just a matter of paint selection. With weight reduction, shapes have become more complex, increasing ribs, holes, corners, and thin sections, making it easier for cleaning agents and moisture to remain. Even if the surface is clean at the time of shipment, peeling can become apparent during assembly or storage. ■Improvement Measures: Treat aluminum as a material where quality differences arise during pretreatment, managing degreasing, surface adjustment, and drying with numerical records. In the event of peeling, revert to check the pretreatment, film thickness, and curing conditions of the same lot. Please utilize documents that allow you to verify pretreatment, drying, and film thickness conditions.

Why does rust occur right after preprocessing? The pitfall of the rainy season.

Rust immediately after preprocessing may actually be caused by condensation in the factory. We will explain measures for the rainy season to summer.

Right after the pretreatment, it is already rusting. The rust may be caused by condensation due to humidity. In an environment with 80 percent humidity, the recurrence of rust due to condensation doubles. ────────────── ■ Cause of Occurrence From the rainy season to summer, temperature differences within the factory can easily cause condensation on the surface of materials. The metal surface right after pretreatment is particularly prone to rust, and the condensed moisture directly turns into red rust. ■ The Truth Even if there is no problem with the pretreatment itself, rust can occur simply due to temperature differences in the storage location. Special caution is needed when moving items from an air-conditioned room to the outdoors due to the temperature difference. ■ Improvement Measures Shorten the time from pretreatment to painting, and manage the temperature and humidity of the storage location. If possible, use a dehumidifier to keep humidity below 80 percent. Please refer to the materials for managing pretreatment during the rainy season.
